I agree, it might be the toxins coming out through your pores. I would suggest a really mild cleanser if you don't already use one. If it has BP in it, make sure it is not too much, otherwise it will cause you to break out more.

Also, a lot of people say that their skin seems to get greasy because they are eating greasy food. I personally think it is from cooking the greasy food. I sometimes feel sticky of greasy after frying up a batch of bacon.
